Exploring the efficacy of FAPI PET/CT in the diagnosis and treatment management of colorectal cancer: a comprehensive literature review and initial experience
摘要
FAPI PET/CT, an innovative medical imaging technique, has emerged as a promising method to target fibroblast activation protein (FAP). This novel approach offers numerous benefits, such as increased tumor absorption and reduced background noise. As a result, FAPI PET/CT images demonstrate a favorable ratio of tumor signal to background, allowing for precise tumor staging, characterization, and detection. Given the heightened expression of FAP in colorectal cancer (CRC), FAPI PET/CT has the potential to revolutionize CRC staging, restaging, and monitoring, as well as enhance treatment management and improve patient prognosis. This comprehensive review aims to provide a detailed overview of the current applications of FAPI PET/CT in CRC, while also proposing future research directions, specifically in comparison to the standard FDG PET imaging modality.
